Under the condition that the starting and ending points of railway transportation are determined, it is a transportation mode carried out according to the railway operation diagram.

[0003] Currently, the coal railway transportation scheduling mainly relies on manual plan formulation. The coal transportation scheduling usually adjusts the plan only when unexpected situations occur during the transportation process, rather than predicting risks in advance and optimizing the scheduling plan. This approach fails to achieve the transformation from passive response to active prevention, which may lead to coal transportation delays and economic losses. Manual planning is time-consuming and laborious, and is easily affected by factors such as weather and personnel fatigue, resulting in low overall transportation efficiency.

[0064] Railway transportation operations generally include two major processes: loaded - vehicle operation and empty - vehicle return. Specifically, it involves business processes such as the operation, formation, decomposition, diversion, return, and retention of trains after loading. Please refer to Figure 2 , Figure 2The schematic diagram of the railway transportation process according to the embodiment of the present application is shown schematically.

[0065] (1) Heavy vehicle operation

[0066] After the train is loaded, it will depart and run in the established direction. Within the integrated scope, the running direction of most heavy vehicles is fixed, and a few stations can choose the direction after the train is dispatched. The train operation is mostly based on a phased planned line, and deviations will be adjusted according to the actual situation of railway transportation.

[0067] (2) Heavy vehicle formation

[0068] In order to give full play to the transportation capacity, improve transportation efficiency and ensure good transportation order during the operation of the train, marshaling operations will be carried out during the operation. Train marshaling is divided into two categories, 10,000-ton marshaling and 20,000-ton marshaling. Train marshaling needs to be carried out at stations with marshaling capacity. For loading stations with 10,000-ton lines, trains can be directly loaded with 10,000 tons and then sent out, but the 10,000-ton lines are limited. For small heavy trains that cannot be sent out with 10,000 tons, they can enter stations with 10,000-ton marshaling capacity for marshaling operations during subsequent operations. In a section, the dispatcher can specify which two small trains will be marshaled to which station after completing loading. In other words, the actual marshaling is planned in advance rather than random, and the marshaling station will get the marshaling plan before the train to be marshaled arrives. When there are sufficient operating tracks and locomotive resources in the station, they all need to be marshaled into 20,000-ton or 16,000-ton trains before they are sent out.

[0069] (3) Diversion unloading

[0070] For example: train diversion mainly includes two directions: Dazhun and Shuohuang. The diversion ports in the Dazhun direction include Datong East, Tanggongta, and power plants along the line east of Waixigou; the diversion ports in the Shuohuang direction include Xibaipo, Dingzhou West, Cangzhou West, Li Tianmu and other diversion ports along the line, Wangzuo and Suning two national railway diversion ports, Huangwan Line and Huangda Line railway diversion, and northern port diversions such as Huanghua Port and Tianjin Coal Terminal. The diversion in the Shuohuang direction is the responsibility of the Suning Office of the Sales Group. The diversion plan is updated approximately every 4 hours based on the diversion port's vehicle model, quantity, coal type and other requirements. The train runs to the planned diversion port according to the diversion plan, and unloads the car after arriving at the diversion port.

[0071] (4) Heavy vehicle disassembly

[0072] During the operation of trains, it is necessary to determine whether the trains need to be uncoupled according to the diversion capacity of the diversion point and the receiving and unloading capacity of the unloading station. Heavy-haul trains are preferentially diverted to stations that meet the train-receiving conditions without being uncoupled. However, when the diversion point does not have the capacity to receive trains of 10,000 tons or 20,000 tons, it is necessary to complete the uncoupling operation at a station with uncoupling capacity before diversion. All 20,000-ton stations have uncoupling capacity. When performing the uncoupling operation, in addition to considering whether the station has uncoupling capacity, it is also necessary to consider whether there are idle operation tracks and uncoupling locomotive resources. Except for unloading along the line, the unloading at the port needs to be uncoupled at the corresponding pre-port station, and the uncoupling needs to consider the train types that can be unloaded by the port tippler and the resource occupancy situation.

[0073] (5) Empty car return

[0074] Trains that have completed unloading need to complete the formation of 20,000-ton or 10,000-ton trains as much as possible before departure according to the formation capacity of the station where they are located. When the formation capacity in the station is insufficient, they can depart in small trains and complete the formation of empty cars at stations along the line with formation capacity. The 20,000-ton empty cars in the Shuohuang direction need to be uncoupled into 10,000-ton trains after arriving at Shenchinan. The railway will comprehensively consider the loading capacity and loading plan of the loading station, pre-arrange an empty car return plan, allocate target loading stations for the empty cars, and then make temporary adjustments according to the time situation on the line. When the allocated empty car return station does not have the capacity to receive 10,000-ton trains, before arriving at the target loading station, the train needs to perform an uncoupling operation at a station with uncoupling capacity and then be sent to the loading station after completion of uncoupling.

[0075] (6) Retention

[0076] Based on the daily outline plan, the railway will execute the retention of heavy-haul and empty cars according to the actual traffic flow and unloading capacity. When the downstream receiving and unloading capacity does not meet the unloading demand, it will coordinate with the sales company to adjust the trains diverted to this station to other unloading points or ports for unloading, or retain some vehicles along the line to ensure that the railway can complete the diversion and loading at the fastest speed after returning to normal. In addition, too many trains in operation on the line, insufficient coal sources, and fluctuations in sales conditions will all cause the trains to go through the retention process.

[0077] Based on the above processes, this solution mainly conducts transportation control through the loading plan, diversion plan, and related rule constraints.

[0078] Please refer to Figure 1 , Figure 1 which schematically shows a flowchart of a railway transportation control method according to an embodiment of the present application. This embodiment provides a railway transportation control method, including the following steps:

[0079] Step 210: Obtain train information;

[0080] In this embodiment, the train information includes information such as train type, type of loaded goods, and weight of loaded goods.

[0081] Step 220: When the train enters the stage of heavy-haul operation, obtain the information of the split unloading points in real time, and based on the information of the split unloading points and the train information, determine the target station according to the preset split unloading model, and control the train to run towards the target station;

[0082] In this embodiment, the above-mentioned heavy-haul operation stage refers to the operation stage after the train is loaded and departs. The above-mentioned information of the split unloading points includes the information of each split point and the unloading station, specifically including the freight information of each split unloading point, the daily split data, etc. The information of the split unloading points can be obtained in real time to obtain accurate information of the split unloading points.

[0083] In some embodiments, the determining the target station according to the preset split unloading model based on the information of the split unloading points and the train information includes:

[0084] First, calculate the daily split plan completion rate of each split unloading point respectively based on the daily split data of each split unloading point;

[0085] In this embodiment, the above-mentioned daily split data includes the actual split volume and the split plan volume, and the calculation of the plan completion rate of the split unloading point can be obtained by using the actual split volume / the split plan volume.

[0086] Then, sort the split unloading points based on the daily split plan completion rate of each split unloading point to obtain a split unloading point sequence;

[0087] In this embodiment, the above sorting can be performed in ascending order or descending order according to the daily split plan completion rate, and this embodiment does not make a limitation.

[0088] Finally, according to the split unloading point sequence, based on the train information and the freight information of each split unloading point in turn, determine whether each split unloading point meets the preset split unloading rules to obtain the target station.

[0089] In this embodiment, the above-mentioned freight information includes information such as the type of goods, the acceptable vehicle types, and the remaining split / loading capacity. The above-mentioned preset split unloading rules can be set in advance, including: whether the split point has the remaining split / loading capacity, whether it can accept this vehicle type, and whether there is a train waiting to be split with the loaded goods. When making the judgment, it can be compared according to the freight information and the train information to determine whether the above split unloading rules are met. If so, it is determined as the target station, otherwise, it is not.

[0090] By calculating the completion rate of the daily diversion plan for each diversion unloading point, sorting each diversion unloading point based on the completion rate of the daily diversion plan for each diversion unloading point to obtain a sequence of diversion unloading points, and successively judging whether each diversion unloading point meets the preset diversion unloading rules based on the train information and the freight information of each diversion unloading point according to the sequence of diversion unloading points, the target station can be quickly determined.

[0091] In some embodiments, in order to quickly determine the optimal target station, the step of successively judging whether each diversion unloading point meets the preset diversion unloading rules based on the train information and the freight information of each diversion unloading point according to the sequence of diversion unloading points to obtain the target station includes the following steps:

[0092] Step A1: Take the diversion unloading point with the lowest completion rate of the daily diversion plan in the sequence of diversion unloading points as the current diversion unloading point;

[0093] Step A2: Based on the freight information of the current diversion unloading point and the train information, judge whether the current diversion unloading point meets the preset diversion unloading rules;

[0094] Step A3: When it is determined that the current diversion unloading point meets the preset diversion unloading rules, take the current diversion unloading point as the target station;

[0095] Step A4: When it is determined that the current diversion unloading point does not meet the preset diversion unloading rules, take the next diversion unloading point as the current diversion unloading point in the order of the completion rate of the daily diversion plan from low to high in the sequence of diversion unloading points, and jump to execute Step A2.

[0096] In this embodiment, starting from the diversion unloading point with the lowest completion rate of the daily diversion plan, it can be first judged whether the diversion unloading point has remaining diversion / loading capacity, whether it can receive this vehicle type, and whether it needs the loaded goods of the train to be diverted. If all the above three conditions are met, enter the next step, set the diversion unloading point as the target station of the train, and the train runs towards the target station; otherwise, judge the station with the second lowest completion rate of the diversion plan, and the diversion unloading point that meets the preset diversion unloading rules and has the lowest completion rate of the daily diversion plan can be quickly determined, so as to determine the optimal target station.

[0097] Step 230: When the train enters the empty car running stage, real-time obtain the information of each loading station, and determine the target loading station according to the preset empty car return model based on the train information and the information of each loading station, and control the train to run towards the target loading station.

[0098] In this embodiment, the above-mentioned empty car running stage refers to the running stage of the train that has completed unloading. The above-mentioned loading station information refers to the information of the stations where loading can be carried out, including information such as the remaining daily loading plan volume, the remaining daily loading volume, and the loadable vehicle types. The information of each loading station can be obtained in real time to obtain accurate loading station information.

[0099] In some embodiments, determining the target loading station based on the train information and the information of each loading station according to a preset empty car return model includes:

[0100] First, based on the information of each loading station respectively, determine the loading indicators of each loading station;

[0101] In this embodiment, the loading indicator of a loading station can be obtained by the remaining daily loading plan volume / the remaining daily loading volume. The loading indicator can represent the urgency of loading. The larger this value is, the higher the urgency of loading.

[0102] Then, based on the loading indicators of each loading station, sort each loading station to obtain a loading station sequence;

[0103] In this embodiment, the above sorting can be carried out in ascending order or descending order of the loading indicators. This embodiment does not make a limitation.

[0104] Finally, according to the loading station sequence, based on the train information and the information of each loading station in turn, judge whether each loading station meets the preset loading rules to obtain the target loading station.

[0105] In this embodiment, the above-mentioned freight information includes information such as cargo type, loadable vehicle types, remaining diversion / connection capacity, etc. The above-mentioned preset loading rules can be set in advance and include: whether the loading station has remaining loading capacity and whether it can receive this vehicle type. When making the judgment, it can be compared according to the freight information and the train information to judge whether the above loading rules are met. If so, it is determined as the target loading station; otherwise, it is not.

[0106] By determining the loading indicators of each loading station, sorting each loading station based on the loading indicators of each loading station to obtain a loading station sequence, and according to the loading station sequence, based on the train information and the information of each loading station in turn, judging whether each loading station meets the preset loading rules, the target loading station can be quickly determined.

[0107] In some embodiments, the step of judging whether each loading station meets the preset loading rules according to the loading station sequence, based on the train information and the information of each loading station in turn to obtain the target loading station includes the following steps:

[0108] Step B1: Use the loading station with the highest loading index in the loading station sequence as the current loading station;

[0109] Step B2: Based on the current loading station information and the train information, determine whether the current loading station meets the preset loading rules;

[0110] Step B3: When it is determined that the current loading station meets the preset loading rules, use the current loading station as the target loading station;

[0111] Step B4: When it is determined that the current loading station does not meet the preset loading rules, use the next loading station as the current loading station in the order of decreasing loading index in the loading station sequence, and jump to execute Step B2.

[0112] In this embodiment, it can start from the loading station with the highest urgency. First, determine whether the loading station has remaining loading capacity and can receive the vehicle type. If both conditions are met, proceed to the next step, set the target loading station of the train as this station, and the train runs towards the target loading station; otherwise, judge the station with the second lowest loading urgency, and it can quickly determine the loading station that meets the preset loading rules and has the highest loading urgency, thereby determining the optimal target loading station.

[0113] In the above implementation process, by obtaining train information; when the train enters the loaded train operation stage, obtaining the shunting unloading point information in real time, and based on the shunting unloading point information and the train information, determining the target station according to the preset shunting unloading model, and controlling the train to run towards the target station; when the train enters the empty train operation stage, obtaining the information of each loading station in real time, and based on the train information and the information of each loading station, determining the target loading station according to the preset empty train return model, and controlling the train to run towards the target loading station. By setting the preset shunting unloading model in the loaded train operation stage and the preset empty train return model in the empty train operation stage respectively, the problems of shunting and empty train return in railway transportation are solved. The various rules in the railway transportation process scenario can be reflected in the model, solving the problem of high dependence on manual experience in coal railway transportation scheduling, improving the optimization and adjustment ability of railway transportation scheduling, flexibly and systematically coping with plan deviations, improving railway transportation efficiency, and reducing transportation costs.

[0114] In some embodiments, the following steps are further included:

[0115] First, obtain the latest same-day shunting data of each shunting unloading point;

[0116] Then, based on the latest same-day shunting data of each shunting unloading point, determine whether each shunting unloading point has completed the same-day shunting plan;

[0117] Then, when it is determined that the daily diversion plans of all the diversion unloading points are completed, based on the next-day diversion plan data of all the diversion unloading points, update the daily diversion data of all the diversion unloading points;

[0118] Then, when it is determined that the daily diversion plans of all the diversion unloading points are not all completed, based on the overage / shortage of the diversion plan of the diversion unloading points that have not completed the daily diversion plan, update the next-day diversion plan data of the diversion unloading points that have not completed the daily diversion plan.

[0119] In this embodiment, the above-mentioned overage / shortage of the diversion plan = the actual diversion volume at the diversion port - the planned diversion volume. When the daily plans of all the diversion ports and unloading stations are completed, use the next-day plan as the basis for diversion, that is, update the daily diversion data; when the daily diversion plan is not completed, accumulate the daily diversion plan into the next-day diversion plan and continue to execute.

[0120] By judging whether all the diversion unloading points have completed the daily diversion plan based on the latest daily diversion data of all the diversion unloading points, when it is determined that all the diversion unloading points have completed the daily diversion plan, based on the next-day diversion plan data of all the diversion unloading points, update the daily diversion data of all the diversion unloading points; when it is determined that all the diversion unloading points have not all completed the daily diversion plan, based on the overage / shortage of the diversion plan of the diversion unloading points that have not completed the daily diversion plan, update the next-day diversion plan data of the diversion unloading points that have not completed the daily diversion plan, so as to ensure the correctness and reliability of the diversion.

[0121] In some embodiments, it further includes:

[0122] First, obtain the latest daily loading data of all the loading stations;

[0123] Then, based on the latest daily loading data of all the loading stations, judge whether all the loading stations have completed the daily loading plan;

[0124] Then, when it is determined that all the loading stations have completed the daily loading plan, based on the next-day loading plan data of all the loading stations, update the daily loading data of all the loading stations;

[0125] Then, when it is determined that all the loading stations have not all completed the daily loading plan, based on the uncompleted quantity of all the loading stations, update the next-day diversion plan data of all the loading stations.

[0126] In this embodiment, when the daily plans of all the loading stations are completed, use the next-day plan as the basis for empty return allocation, that is, as the daily loading data; for the stations where the daily loading plan is not completed, accumulate the uncompleted planned quantity into the next-day plan and continue to execute.

[0127] By obtaining the latest daily loading data of each loading station; based on the latest daily loading data of each loading station, determining whether each loading station has completed the daily loading plan, and in the case of determining that each loading station has completed the daily loading plan, updating the daily loading data of each loading station based on the next-day loading plan data of each loading station; in the case of determining that each loading station has not completed the daily loading plan, updating the next-day diversion plan data of each loading station based on the uncompleted quantity, so as to ensure the correctness and reliability of loading.

[0128] The following is illustrated with a specific example. Please refer to Figure 3 and Figure 4 , Figure 3 which schematically shows the railway operation process according to an embodiment of the present application Figure 1 ; Figure 4 which schematically shows the railway operation process according to an embodiment of the present application Figure 2 .

[0129] First, a judgment on the formation requirement is made for the loaded freight trains that have completed loading. If formation is required, the trains enter the corresponding station according to the formation rules to complete the ten-thousand-ton or twenty-thousand-ton formation operation. If formation is not required or the formation cannot be completed before diversion, then a judgment on the diversion and unloading requirement is entered. According to the diversion plan and diversion rules, a suitable diversion port or unloading station is matched for the train. When the receiving capacity of the diversion port and the unloading station does not conform to the attributes of the train to be diverted, before the diversion and unloading operation, according to the breakup rules, a station with breakup capacity is searched along the line to enter the station to complete the breakup operation of the train and then send it out for diversion and unloading operations. In addition to the above process, when the heavy-car retention condition is triggered during the transportation process, according to the heavy-car retention rules, the train to be diverted needs to find a station with retention capacity to enter the station for retention until the retention condition is lifted and then go online and send out. Before the train departs, according to the heavy-car operation rules, the interval capacity is judged to decide whether it can be sent out immediately.

[0130] For the empty cars that have completed unloading and entered through the diversion port, formation needs to be given priority. According to the empty-car formation rules, a station with formation capacity is searched to complete the ten-thousand-ton and twenty-thousand-ton empty-car formation operations. If the allocated loading station does not have the ten-thousand-ton receiving capacity, the train needs to find a station with breakup capacity during the empty-car return journey to perform the breakup operation according to the empty-car breakup rules and enter the loading station in the form of a small train.

[0131] In addition to the above process, when the empty-car retention condition is triggered during the transportation process, according to the empty-car retention rules, the empty cars to be loaded need to find a station with retention capacity to enter the station for retention until the retention condition is lifted and then go to the station for loading. Before the train departs, according to the requirements of the interval capacity in the empty-car operation rules, it is judged whether the empty car can be sent out immediately.

[0132] It should be noted that the above railway transportation control method depends on the network collaboration relationship in the railway transportation link. Please refer to Figure 5 , Figure 5 which schematically shows the network collaboration relationship diagram of the railway transportation link according to the embodiments of the present application.
